Be it known that I, CHARLES L. KINNEY, a citizen ofthe United States;L residing at Coalinga, inthe county` of 1*`resno,f Statev of.

anchor shortrarm Q2 ing` the tubing, either the long or short arm of`each slot may be brought above the-corand securely attached thereto, is a tube or sleeve 14 which surrounds the tubing imnie- This tube 1d 1 may vhave apertures 15 at itsuper end for diately beneath the eollar.

circnlationof liquid., ,Thev tu e 14 constitutesthesupporting member or foundation of my supporter-A and catcher are mounted.

upon which the movable parts Moiuited about the tube 14 1 supply the friction anchor 16. this anchor comprises a lower ring 17, an

yupper ring 18, and a plurality of bowed vspring members 19 adapted to press outwardly against the inside of the casing and tro/create suflicient friction to support the' 'anchor'and the parts supported thereon in any position in the casing-but-not suiiicient friction to prevent ready movement rof ln its preferred form v ,aI/{other jointV screws upwardly in the. usual the tubing in the casing.' 'The friction an- Chor is connected with the sleeve 14 through `the mediumr of a pair of pins or studs 2O carried by the lower ring 17 and engaging in slots 21.A The slots 9.1 are preferably two in number and'located on opposite sides of the sleeve 14 (althongh the number may be as desired); and each of theslots 21 hasaand a long arm 23. By turnresponding stud 21. In F ig. 1 the partsare shown in an intermediate position. When the supporter is beinglowered'into a Well. the studs are placed in the short arms 22 of vthe slots andgthe frictional engagement of the springs 19 with the casing tends to hold the studs up in these parts of the slot; and

the anchor is held in about the relative position shown in Fig. 1. fixen the tubing has been lowered to its destination, it is raised a few inches (for enough tocariry the slots up on the studs so that the lower ends of the slots engage the studs) lonfr arms-2`3 .of the slots Without movin C y v,

The movement of the slips is entirely independent of thev expansion and contraction of thelsprings 19, the springs spring flfrests in these mally' compress the slips an fromengagin the casing. T e slipshave the aeial for grppmghb' easing.

`.Insthe' nermalpositien of the device/,fas aproximately shown in Figill, the slips are the eene collar` 1Q. this" tbeiev' is lowered into the casin'gte the 4 tfwre it' is deredtoset theagp orter.

If it is only desired to raise the tubing, it is only necessary to pull upwardly on it`,"not being necessary to turn the tubing. When the tubing is bein raised out of the casing', the studs 21 will ie beneath the'long arms 23' of the slots; and if the tubing. should break and drop any catcher which is below the break wou d catch and su port the tubing. It is designed that the evices may be placed at the top orl bottom of the tubing and in intermediate positions, sc that one or several of them may support the entire wei ht of the' tubing. If therer are several of t e supporters'and catchers-on a string of tubing, -eachfbf the devices only has to upper dat face oftherin'g 18, er. a flange i8` I '-thatring.
